使用go-cqhttp搭建qq机器人

使用go-cqhttp搭建qq机器人--python处理消息

1.环境部署

• 本次使用windows测试部署
• 下载地址：https://github.com/Mrs4s/go-cqhttp/releases

• 下载后解压，会有三个文件，点击运行exe

  • 

• 生成bat文件，再运行

  • 

• 运行bat，填入0，然后生成配置文件config.yml;填入qq号和密码(不过填入密码，一直登陆失败，最后还是选择扫码登陆)

  • 

• 取消倒数三四排的代码注释，开启监听端口api，方便后续操作

  • 

• 打开device.json文件，修改protocol的值为2，否则一直登陆失败

  • 

• 最后再次点击bat文件运行，扫码登陆；显示如下就表示登陆成功以及cqhttp接管qq成功

  • 

2.python代码

• receive.py文件负责监听socket(端口要和上面配置文件中的端口一致)，接收由cqhttp传来的消息；

  import socket
  import json
  
  ListenSocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  ListenSocket.bind(('127.0.0.1', 5701))
  ListenSocket.listen(100)
  HttpResponseHeader = '''HTTP/1.1 200 OK\r\n
  Content-Type: text/html\r\n\r\n
  '''
  
  
  def request_to_json(msg):
      for i in range(len(msg)):
          if msg[i] == "{" and msg[-1] == "\n":
              return json.loads(msg[i:])
      return None
  
  
  # 需要循环执行，返回值为json格式
  def rev_msg():  # json or None
      Client, Address = ListenSocket.accept()
      Request = Client.recv(1024).decode(encoding='utf-8')
      rev_json = request_to_json(Request)
      Client.sendall((HttpResponseHeader).encode(encoding='utf-8'))
      Client.close()
      return rev_json
  
  

• send_msg.py;python后端处理消息后返回的消息由该文件发出

  import socket
  
  port = 5700
  
  
  def send_msg(resp_dict):
      client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  
      ip = '127.0.0.1'
      client.connect((ip, port))
  
      msg_type = resp_dict['msg_type']  # 回复类型（群聊/私聊）
      number = resp_dict['number']  # 回复账号（群号/好友号）
      msg = resp_dict['msg']  # 要回复的消息
  
      # 将字符中的特殊字符进行url编码
      msg = msg.replace(" ", "%20")
      msg = msg.replace("\n", "%0a")
  
      if msg_type == 'group':
          payload = "GET /send_group_msg?group_id=" + str(
              number) + "&message=" + msg + " HTTP/1.1\r\nHost:" + ip + f":{port}\r\nConnection: close\r\n\r\n"
      elif msg_type == 'private':
          payload = "GET /send_private_msg?user_id=" + str(
              number) + "&message=" + msg + " HTTP/1.1\r\nHost:" + ip + f":{port}\r\nConnection: close\r\n\r\n"
      print("发送" + payload)
      client.send(payload.encode("utf-8"))
      client.close()
      return 0
  

• bot.py最关键的文件，负责写一些逻辑，像接收到什么消息返回特点的消息

  import re
  
  from receive import rev_msg
  from send_msg import send_msg
  import socket
  import requests
  import random
  import urllib.request, json
  import other_api
  
  while True:
      try:
          rev = rev_msg()
          print(rev)
          if rev == None:
              continue
      except:
          continue
  
      if rev["post_type"] == "message":
          if rev["message_type"] == "private":  # 私聊
  
              if '在吗' in rev['raw_message']:
                  qq = rev['sender']['user_id']  # 获取消息发出者的qq号
                  send_msg({'msg_type': 'private', 'number': qq, 'msg': '我在'})  # 发送
  
  
  
          elif rev["message_type"] == "group":  # 群聊
              group = rev['group_id']
              if '在吗' in rev['raw_message']:
                  qq = rev['sender']['user_id']
                  send_msg({'msg_type': 'group', 'number': group, 'msg': '你好'})
          else:
              continue
      else:  # rev["post_type"]=="meta_event":
          continue
  
  

• 记得将所有py文件放在同一目录，最后运行bot.py文件

• 一些测试代码：

  •                 elif '热搜' in rev['raw_message']:
                        qq = rev['sender']['user_id']
                        result = other_api.rs()
                        result_rs = ''
                        for i in range(15):
                            t = str(i + 1) + ":" + result[i] + "\n"
                            result_rs = result_rs + t
                        send_msg({'msg_type': 'group', 'number': group,
                                  'msg': result_rs})
    

    def rs():  # 微博热搜
        header = {
            "User-Agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:109.0) Gecko/20100101 Firefox/112.0",

            "Accept-Encoding": "gzip, deflate",
        }
        url = "https://tophub.today/n/KqndgxeLl9"
        res = requests.get(url, headers=header)
        selector = etree.HTML(res.text)
        result = []
        for i in range(30):
            t = selector.xpath(f"/html/body/div[1]/div[2]/div[2]/div[1]/div[2]/div/div[1]/table/tbody/tr[{i + 1}]/td[2]/a")
            result.append(t[0].text)
            # print(i+1, t[0].text)
        return result
